Summary:
We currently have iOS and Android existing app integration guides. I have revamped these into a single tutorial, with three sections: Objective-C, Swift and Android.
For Objective-C and and Swift, the tutorial is now based on a more real world app - integrating a React Native-based high score screen into a 2048 app.
For expediency to get the iOS stuff out, for Android, *for now*, I have kept the existing documentation (with minor updates), but am planning to try to follow the same 2048 model for it as well.
This uses the same toggler as Getting Started
> I do note the copypasta of the toggler code. I am planning another separate pull request to make that more modular and reusable across all areas of the documentation on which it seems reasonable.
